Of the 3 Tomlin is the most likely to remain especially if the Steelers hits a GM from within the organization. If they hire outside of the current staff, which is unlikely because of how they handle business, the chances of Tomlin leaving in 2021 is greater but still not a guarantee.

I don’t see Mike Tomlin going anywhere in 2021 if for some reason that Ben Roethlisberger doesn’t come back in 2021 they have two good back ups at Devlin Hodges and Paxton Lynch I hope the Steelers get smart and realize the Mason Rudolph is garbage at the back up quarterback position
and trade him for a number# 1 draft pick in 2021 now as for Kevin Colbert the Steelers should look for a G.M. that is more aggressive in the draft and stop wasting money on players like Bud Dupree

Not sure how I’m going to handle the news if the three of them leave together. It will be a sad, tough day when Ben leaves. Seems like it took forever for the Steelers to find a franchise QB after Bradshaw. Was such a blessing to get Tomlin right after Cowher. And I can still remember many of the things Colbert and Cowher did to set up the next Steeler dynasty, if you can call it that with all of the free agency changes going on… It will be a really tough day, that much I know.
